enable nested ADT and sequences

Browse source 
add API to define forward reference to recursively defined datatype.
The forward reference should be used only when passed to constructor declarations that are used in a datatype definition (Z3_mk_datatypes). The call to Z3_mk_datatypes ensures that the forward reference can be resolved with respect to constructors.

\brief create a forward reference to a recursive datatype being declared.
The forward reference can be used in a nested occurrence: the range of an array
or as element sort of a sequence. The forward reference should only be used when
used in an accessor for a recursive datatype that gets declared.
Forward references can replace the use sort references, that are unsigned integers
in the \c Z3_mk_constructor call
